This essay reflects on the status of kinesiology amidst the current pandemic and Black Lives Matter movement. Utilizing the metaphor coined by mathematician and physicist Freeman Dyson, I contend ...that the continued success of kinesiology is more plausible if we prepare more visionary birds, those with broader range and a variety of interests, to supplement the more narrowly focused frogs who currently dominate the field. Implicit in the essay is the contention that the field would benefit if it took a more interdisciplinary approach to the study of physical activity, sport, exercise, and other human movement forms as advocated by the American Kinesiology Association and individual scholars in the field. More specifically, I argue that the social sciences and humanities should be provided a more prominent place in kinesiology curriculums and serve as an academic core for all students in the field, irrespective of career aspirations and goals.
The measure characteristics of motoric tests (validity, reliability, objectivity) have always been a subject of interest when it comes to research within kinesiology. The most important problem of ...kinesiology studies and researches is to measure the human reactions and characteristics. The choice of conducting the present type of the study is based on the goal to establish the measure characteristics of motoric tests with 6-grade students. On the base of the received results, it is obvious that regarding the three tests satisfactory measure characteristics are established (validity, reliability and objectivity).
An acute increase in maximum strength, power, or speed following a conditioning contraction known as a postactivation performance enhancement has been previously determined to be better performed ...when the initial exercise is of the same movement pattern. However, no research has been performed studying the effects of a hex-bar farmer’s walk on subsequent sprinting speeds. Therefore, this research examined the use of different loads of a hex-bar farmer’s walk completed at 20-m and their effect on subsequent 20-m sprinting performance. Through a randomized and counterbalanced design, resistance and running trained men and women (n = 12) performed five 20-m sprints (with 10-m splits) at baseline, 4, 8, 12, and 16-minutes after a bodyweight control (C), light farmer’s walk (LFW), and heavy farmer’s walk (HFW), utilizing 70% and 80% users hex-bar deadlift 1-RM respectively. Mean sprint velocities over 10-m and 20-m distances were similar at baseline. At 20-m, sprint velocity significantly increased during the LFW condition at 8 minutes (M = 6.03, SE = 0.14, p = 0.025), 12 minutes (M = 6.05, SE = 0.15, p = 0.016), and 16 minutes (M = 6.03, SE = 0.14, p = 0.011) when compared with C (M = 5.96, SE = 0.14, t(11) = -2.59, r = 0.98); (M = 5.97, SE = 0.15, t(11) = -2.85, r = 0.98); (M = 5.94, SE = 0.14, t(11) = -3.06, r = 0.98, p < 0.05). At 10-m, sprint velocity significantly increased during the LFW condition at 8 minutes (M = 5.10, SE = 0.12, p = 0.010), when compared with C (M = 5.01, SE = 0.12, t(11) = -3.08, p <0.05, r = 0.97). No change to sprinting velocity was witnessed across either of the C conditions or HFW conditions. These results help to substantiate the use of a load at near-maximal capacities during the warm-up preceding sprinting to acutely increase muscular force.
Countermovement jumps (CMJ) are frequently used in strength and conditioning as a key performance indicator. Force platforms are often considered the standard for measuring ground reaction forces ...(GRF) and deriving subsequent performance metrics. Although force platforms are often the standard, they may not always fall within an allotted budget. Jump mats are another option for CMJ testing that are cheaper than the criterion force plates. Although cheaper, jump mats only measure flight time (FT) and jump height (JH), whereas the criterion measures GRF. Therefore, this study looks at the reliability and validity of the Just Jump System compared to the criterion reference ForceDecks force plates during a CMJ with a self-selected depth. This study examined the agreement between the metrics: jump mat FT to force plate FT, jump mat JH to force plate JH, jump mat JH derived by FT to force plate JH derived by impulse. Twelve participants (male n=7 and female n=5 with an average age of 24 years SD 3, average body mass of 83.7 kilograms SD 17.5, average height of 176.2 centimeters SD 11, and an average shoe thickness of 1.8 centimeters SD .5) completed a standardized warmup including a familiarization protocol. Following, the participant completed 5 sets of 5 repetitions of CMJ. Each repetition was followed by a 30 second rest period. Each set of 5 jumps was followed by two minutes of rest. Force plate data was analyzed in the proprietary ForceDecks software, and then exported to excel. Jump mat data was manually recorded on a data collection sheet which was then manually entered into excel. From excel, an interclass correlation coefficient (ICC) and the coefficient of variation (CV) for reliability were calculated. The ICC was reported as .96 and the CV was reported as 9.16%. These results indicated that the Just Jump mats have excellent reliability. For validity, means and standard deviations, a Pearson’s correlation, coefficient of determination, scatter plots, and a Bland-Altman 95% limits of agreement (LOA) were utilized. The means and standard deviations reported by the jump mat were flight time (ms) 541.37 (SD 49.64), jump height (cm) 36.74 (SD 6.79). The means and standard deviations reported by the force platforms were flight time (ms) 446.87 (SD 52.60), jump height derived by flight time (cm) 24.82 (SD 5.91), and jump height derived by impulse (cm) 24.69 (SD 5.83). The Pearson’s correlation indicated a very strong positive relationship with all metrics where force plate FT and jump mat FT (r = 0.991), force plate JH derived by FT and jump mat JH (r= 0.995), force plate JH derived by impulse and jump mat JH (r = 0.974). The Bland-Altman 95% limits of agreement (LOA) analysis between force plate FT and jump mat FT showed a mean bias ± LOA of 1.80 (LOA 14.77 ms). The Bland-Altman 95% LOA analysis between force plate JH derived by FT and jump mat JH showed a mean bias ± LOA of 2.02 (LOA 2.14 cm). The Bland-Altman 95% LOA analysis between force plate JH derived by impulse and jump mat JH showed a mean bias ± LOA of 2.07 (LOA 3.37 cm). The Just Jump mat overestimates FT, and thus, overestimates JH. Although reliable, the Just Jump mats are not valid in comparison to the criterion force plates.
In today’s challenging economic climate at most universities, kinesiology administrators are becoming increasingly aware of the need to participate in activities that will generate alternative ...revenue sources related to their academic mission. The ways deans and development officers communicate with alumni, potential donors, upper administrative leaders, and legislatures will all impact how successful the efforts to develop funds and partnerships will be. Successful fundraisers are those who can generate strategic alliances, create and market a plan that relates needs to societal issues of public interest and university priorities, and are able to identify partnerships that will produce an increase in resources. This paper provides strategies for identifying and connecting with key donors, building partnerships, developing the plan and cultivating internal and external audiences, aligning needs with university priorities, and working with legislatures.
HintergrundZur Bestimmung der therapeutischen Impulsrichtung bei der Atlastherapie nach Arlen gilt die Anfertigung einer a.-p.-Röntgenaufnahme des zervikookzipitalen Übergangs traditionell als ...unverzichtbar. Überlegungen zum Strahlenschutz sowie technische und ökonomische Aspekte förderten die Suche nach einer klinischen Methode, die in der Lage ist, die radiologische Untersuchung zu ersetzen. Zur Diskussion stand der manualdiagnostische 3-Zeichen-Test nach CoenenMethodikDie Zuverlässigkeit des 3-Zeichen-Tests wurde an 438 neurologisch gesunden Patienten mit Funktionsstörung der oberen Halswirbelsäule (HWS) untersucht. Das Testergebnis jedes einzelnen Patienten wurde mit der Analyse seiner Atlas-a.-p.-Röntgenaufnahme verglichen. Jeder Patient erhielt die Atlastherapie nach Arlen gemäß dem 3-Zeichen-Test-Ergebnis; die Bestimmung der Sensitivität des Tests erfolgte aus dem Therapieergebnis nach einmaliger Behandlung.ErgebnisseEine Übereinstimmung des 3-Zeichen-Tests mit der Röntgenbildanalyse ergab sich bei 84,6 % der untersuchten Patienten, keine Übereinstimmung fand sich bei 8,5 % und unklar blieben 6,3 %. Eine Bestätigung des Tests durch das Therapieergebnis nach einmaliger Behandlung wurde bei 94,5 % der Patienten ermittelt, bei 5,3 % fand sich keine Bestätigung.SchlussfolgerungBei der Bestimmung der atlastherapeutischen Impulsrichtung erwies sich der 3-Zeichen-Test als mindestens gleichwertig mit der Röntgenbildanalyse. Der Test kann somit die rein therapeutisch indizierte Röntgenuntersuchung des zervikookzipitalen Übergangs ersetzen und leistet einen wichtigen Beitrag zur Minderung der Strahlenexposition. Er ist kein Ersatz für eine diagnostische Röntgenaufnahme zum Ausschluss pathologischer Prozesse an der HWS bei auffälliger Anamnese und suspekter Symptomatik.
